Description

Technical Field

[0001] This utility model belongs to the field of LED lampshade technology, specifically, it relates to an optical scattering LED lampshade. Background Technology

[0002] LED lampshades are a type of LED lighting accessory designed to better focus light, making it more concentrated and softer, and preventing direct, glaring LED light. The main function of a milky white lampshade is to diffuse light more softly and evenly into space without causing glare. Its light transmittance must be within a certain range to prevent excessive light waste inside the shade, while also allowing light to be diffused through the film layer into every space, ensuring that the internal LED chips are not visible while maximizing the dispersion of light.

[0003] To create a warm and comfortable atmosphere, frosted acrylic sheets are usually installed at the bottom of LED lampshades to soften the light emitted by the LEDs. The surface of the frosted acrylic sheet undergoes a special treatment to create a frosted effect. Compared to traditional transparent acrylic sheets, the frosted surface effectively scatters light, reducing the glare from direct light and creating a warm and comfortable atmosphere. This characteristic makes frosted acrylic sheets very popular in situations requiring soft lighting. However, frosted acrylic sheets are usually fixed to the bottom of the LED lampshade. When the LED malfunctions, the entire lampshade shell needs to be disassembled to repair or replace the LED, making the repair or replacement process cumbersome. Therefore, this utility model proposes an optically scattering LED lampshade to solve the above problems. Utility Model Content

[0004] To address the problem that frosted acrylic sheets are mostly fixed to the bottom of LED lamp covers during installation, requiring the entire lamp cover to be disassembled for repair or replacement when the LED malfunctions, which is cumbersome, the basic concept of this utility model is as follows:

[0005] An optical scattering LED lampshade includes a lampshade housing with a frosted acrylic plate mounted on the bottom. The bottom of the lampshade housing has equidistantly distributed positioning mechanisms, each including a fixing plate and a mounting base. The fixing plate has a rectangular opening at its bottom, and the mounting base is fixedly connected to the inner wall of the rectangular opening. The mounting base has a movable groove at its top, and a wedge-shaped support block is slidably disposed on the inner wall of the movable groove. The top of the support block contacts the bottom outer wall of the frosted acrylic plate. A guide rod is fixedly connected to one side of the outer wall of the support block, with one end extending to the outside of the mounting base. A push-pull plate is rotatably mounted on the end of the guide rod located outside the mounting base. A baffle is fixedly connected to one side of the outer wall of the fixing plate, and a limiting groove is formed at the end of the baffle. The push-pull plate and the limiting groove are compatible.

[0006] In a preferred embodiment of this utility model, a through hole is provided on one side of the mounting base, the movable groove communicates with the through hole, and the guide rod is slidably connected to the inner wall of the through hole.

[0007] In a preferred embodiment of this utility model, a compression spring is fixedly connected to the inner wall of one side of the movable groove, one end of the compression spring is fixedly connected to the outer wall of one side of the support block, and the compression spring is sleeved on the guide rod.

[0008] In a preferred embodiment of this utility model, an annular mounting plate is fixedly provided on the top of the lampshade housing, and the annular mounting plate has mounting holes that are evenly distributed.

[0009] In a preferred embodiment of this utility model, a circular mounting opening is provided at the bottom of the lampshade housing, and the frosted acrylic plate is mounted on the inner wall of the circular mounting opening.

[0010] In a preferred embodiment of this utility model, the bottom inner wall of the lampshade housing is fixedly connected with symmetrically arranged limiting plates, and the bottom of both limiting plates is in contact with the top outer wall of the frosted acrylic plate.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] This invention features a frosted acrylic plate that softens the light when the LED light is turned on, effectively scattering the light and reducing the glare from direct sunlight to create a warm and comfortable atmosphere. When the LED light malfunctions, pulling the sliding plate laterally moves the guide rod, which in turn moves the support block laterally, disengaging it from the bottom of the frosted acrylic plate. The sliding plate is then flipped and moved into a limiting groove, where a baffle acts as a limit. The frosted acrylic plate can then be removed from the bottom of the lampshade. After removal, the LED light inside the lampshade can be inspected or replaced without disassembling the entire lampshade, facilitating maintenance and replacement work.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0021] like Figures 1 to 4 As shown

[0022] An optically diffused LED lampshade includes a lampshade housing 1. A frosted acrylic plate 2 is mounted on the bottom of the lampshade housing 1. The frosted acrylic plate 2 softens the light, effectively scattering it and reducing the glare from direct light, creating a warm and comfortable atmosphere. The bottom of the lampshade housing 1 is equipped with equidistantly distributed positioning mechanisms 3, including a fixing plate 7 and a mounting base 9. The fixing plate 7 has a rectangular opening at its bottom, and the mounting base 9 is fixedly connected to the inner wall of the rectangular opening. The top of the mounting base 9 has a movable groove 14, and a wedge-shaped support block 8 is slidably disposed on the inner wall of the movable groove 14. The top of the support block 8 contacts the bottom outer wall of the frosted acrylic plate 2. A guide rod 10 is fixedly connected to one side of the outer wall of the support block 8. One end of the guide rod 10 extends to the outside of the mounting base 9, and a push-pull plate 11 is rotatably mounted on the end of the guide rod 10 located outside the mounting base 9. A baffle 12 is fixedly connected to one side of the outer wall of the 7th section. A limiting groove 13 is opened at the end of the baffle 12. The push-pull plate 11 is adapted to the limiting groove 13. A compression spring 15 is fixedly connected to one side of the inner wall of the movable groove 14. One end of the compression spring 15 is fixedly connected to one side of the outer wall of the support block 8. The compression spring 15 is sleeved on the guide rod 10. When the LED lamp body malfunctions, the push-pull plate 11 is pulled to move laterally. The push-pull plate 11 drives the guide rod 10 to move laterally. The guide rod 10 drives the support block 8 to move laterally, so that the support block 8 is separated from the bottom position of the frosted acrylic plate 2. Then the push-pull plate 11 is flipped. After the flipping is completed, the push-pull plate 11 is moved into the limiting groove 13, so that the baffle 12 plays a limiting role on the push-pull plate 11. Then the frosted acrylic plate 2 can be removed from the bottom position of the lamp cover shell 1. After the removal is completed, the staff can inspect or replace the LED lamp body inside the lamp cover shell 1.

[0023] In a specific embodiment, a through hole is provided on one side of the mounting base 9, the movable groove 14 communicates with the through hole, and the guide rod 10 is slidably connected to the inner wall of the through hole. An annular mounting plate 4 is fixedly provided on the top of the lampshade housing 1. The annular mounting plate 4 has equidistantly distributed mounting holes 16. The lampshade housing 1 is fixedly installed on the wall by screws through the annular mounting plate 4 and the mounting holes 16, so that the LED lamp body installed on the wall is located inside the lampshade housing 1. A circular mounting opening 5 is provided at the bottom of the lampshade housing 1. The frosted acrylic plate 2 is installed on the inner wall of the circular mounting opening 5. Symmetrically arranged limiting plates 6 are fixedly connected to the bottom inner wall of the lampshade housing 1. The bottom of both limiting plates 6 are in contact with the top outer wall of the frosted acrylic plate 2.

[0024] The implementation principle of an optical scattering LED lampshade in this embodiment is as follows:

[0025] In practical use, the lampshade housing 1 is fixed to the wall using the ring mounting plate 4 and mounting holes 16 with screws, so that the LED light body installed on the wall is located inside the lampshade housing 1. When the LED light body is turned on, the frosted acrylic plate 2 can soften the light, effectively scattering the light and reducing the glare from direct light, creating a warm and comfortable atmosphere. When the LED light body malfunctions, the push-pull plate 11 is pulled horizontally, which in turn moves the guide rod 10 horizontally, causing the support block 8 to detach from the bottom of the frosted acrylic plate 2. Then, the push-pull plate 11 is flipped over and moved into the limiting groove 13, where the baffle 12 limits the push-pull plate 11. The frosted acrylic plate 2 can then be removed from the bottom of the lampshade housing 1. After removal, the LED light body inside the lampshade housing 1 can be inspected or replaced.
